Exploring Earth-like Planets and the Search for Extraterrestrial Life

What is the ultimate goal of NASA's exoplanet mission?

• To discover new stars

• To find new galaxies

• To find evidence of active life on planets outside our solar system

• To explore the surface of Mars

Which telescope is known for providing rudimentary proof of possibly habitable planets?

• Hubble Space Telescope

• James Webb Space Telescope

• Chandra X-ray Observatory

• Kepler Space Observatory

What is a key factor for a planet to be considered in the habitable zone?

• Presence of mountains

• Presence of liquid water

• Presence of a magnetic field

• Presence of an atmosphere

Which exoplanet is closest to Earth in terms of distance?

• Kepler-452b

• Proxima Centauri

• Trappist-1e

• Kepler-22b

Which exoplanet is known to orbit a red dwarf star and is 4.5 times the size of Earth?

• Gliese 667 Cc

• Kepler-69c

• Kepler-1649c

• Kepler-442b

What method is primarily used by the Kepler spacecraft to detect exoplanets?

• 20%

• 100%

• 50%

• 80%

What is a necessary condition for a star to support life on its planets?

• It must be stable and not prone to flares

• It must be a red giant

• It must have a strong magnetic field

• It must be part of a binary system
